Be it known that I, lEnasrus E. l/ViNKLEY, a citizen of the UnitedStates, residing at Lynn, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inSole-Pressing tion of the in'ventio11,fsuch as Will enablel othersskilled in `the art to which it apper- The present invention relates tosolve pressf 111g machines Whlch are used 1n the manufacture of bootsand shoes to perform the More particularly the present yinventionextensively used to perform the sole leveling operation, Which comprisesa shoe supporting jack, a cooperating sole pressing form, and means foractuating the jack and form to subject the sole of a shoe supported uponthe jack to a rolling pressure.

Rolling pressure sole leveling machines are usually constructed to exerttwo pressures upon the sole of a shoe, one pressure being produced bythe inward movement of the jack and form from a position at thenfront ofthe machine in Which a shoe can be readily removed from the Ijack andanother shoe placed thereon, which position is termed a position ofpresentation, and another pressure being produced during the returnmovement of the jack .andform to the position ever, to subject the soleto a greater number accomplished by starting and stopping the machineseveral times without removing -the shoe from the jack., Machines have,:how-l ever` been devised by'Which the jackandl form are automatically*and continuously moved to produce this result, and in an lapthel machinedisclosed in said application which I am familiar, the number ofpressures to which the sole is subjectedy is predetermined by `thelconstruction of themachine or isdependent ufponpthe will of theoperator.

i ERASTUS E. WINKLEY, OF LYNN, MASSACHUSETTS, .ASSIGNOR T0 UNITED SHOENEW JERSEY, A CORPORATION OF NEW SOLE-PRESSING 'MACHINE Patented Nov. 9,1909. Renewed March 12, isos. seria1N0.42o,e93.

Varies with the thickness of the sole, and an object of my invention isto provide a sole pressing machine by Which soles of differentthicknesses will be subjected to the required number of pressures. Withthis object -in View, my invention broadly considered contemplatesproviding a sole pressing machine comprising a jack and ajfo'rm andmeans for relatively actuating the jack and form to press the sole of ashoe supported upon the jack with means controlled by the thicknessofthe sole of a shoe for determining the number of pressing operationsto Which the sole is subjecte I believe that I am the first in the artto provide a'sol'epressing machine of any description in Which thenumber of pressures exerted upon the sole of a shoe 1s determined by thethickness of the sole, and I therefore consider this feature of myinvent-ion as broad and generic in character and as capable ofembodiment in otherxforms ofsole pressing machines as well as in thatform in which the sole is subjected to a rolling pressure. VVhilethisfeature of my invention broadly considered may be embodied in any solepressing machine `comprising a shoe supportingjack and' a cooperatingsole pressing form, it is preferably embodied in 'a machine in which thejack and form are actuated to subject the sole of a shoe to a rollingpressure as it is of specialimportance lin this class of machines tosubject the sole to .a number of pressures to beat out` or level thesole.

In the machine disclosed in my application above referred to and in allother rolling pressure sole leveling machines With Which I am familiarin which mechanism'is provided which operates to move the jack vandform'to'subject the sole of a shoe supported upon the jack to aplurality '0f rolling pressures and in which the jack is stoppedautomatically in a position of pres-l entation, no means forming -apermanent part of the machine are provided for varying the'numberof'pressing operations to properly7 which the sole` is subjected, thesame number ofv pressures being exerted upon a thin -sole'as upon athick sole.' I believe that I am the first to providel suclra machinewith meansl permanently embodied therein for varying th-e number ofpressing operations Qto which the sole is subjected Whether such nieans-are controlled by the thicklfcss of the `forming a ypermanent soleof a shoe or are controlled by any other means or by the operator, and Iaccordingly consider a feature of my invention to consist in providing asole pressing machine.

comprising mechanism acting to move a jack 'and form to subject the soleof a shoe to a plurality of rolling'pressures, and meansl actingAautomatically to stop the jack in a position .of presentation, with anymeans part of the machine for varying the number of pressing operationsto which the sole is subjected.

The machine which I have disclosed herein as embodying my invention inits pre.'-

-ferred form in addition to the broad features of invention abovereferred` to embodies other features of invention hereinafter dejscribed and claimed, the advantages of which 'will be obvious to thoseskilled in the art. As to these features of invention it is tobeunderstood that except as specifically dened inthe claims they are notlimited to any particular construction or arrangement of parts but maybe embodied in constructions other thanthose illustrated and hereinafterdescribed without departing from the spirit thereof.

The machine illustrated in the drawings is a duplex rolling pressuresole leveling machine ofthe same general type as the sole levelingmachine disclosed in United States patent toTripp No. 296,486, datedApril 8,

Fig. 7 is a detail sectional viewl 1884. The machine comprises twopivotally mounted arms upon which the sole pressing forms are supportedand two pivotally mounted arms upon which the shoe supporting jacks aresupported, the arrangement of the arms beingl such that when two of thearms supporting .a jaclg and a cooperating form respectively areoscillated the sole of the shoe supported upon the jack is subjected toa rolling pressure. The two sets of arms are oscillated by means of acommon actuating mechanism which comprises a driving shaft, throughconnections between the driving shaft and the arms. The driving shaft isrotated alternately in opposite directions, means the reversals in thedirection of rotation are produced automatically, and the connectionsbetween the driving shaft and the pivotally mounted arms are such thatthe direction of the oscillation of the arms is changed with eachreversal in the direction of rotation of the driving shaft.` When themachine is at rest the pivoted arms are at the extreme limit of theirforward movement, the jacks and forms being separated to allow shoes to4,be removed from or placed upon the jacks.

During the operation of the machine one pair of arms upon which a jackand its cooperating form are supported are moved from the position atthe front of the machine, which position is termed a position ofpresentation, toward the rear of the machine to subject the sole of theshoe supported upon the jack to a rolling pressure and are then eitherreturned to the position of presentation at the front of the machinethereby subjecting the sole of kthe shoe to another rolling pressure, orare moved forward and baclrone or more times through a lesser varc tosubject the sole of the shoe to a number of rolling pressures and thenfinally returned to the position of presentation at the front ofthemachine.l During the movement of one jack and its cooperating form tolevel being provided by which th'e sole of a shoe the arms supportingthe other jack and form are disconnected from the actuating mechanism,means being provided for connecting and disconnecting each set of armsand the actuating mechanism so that one jack and form can remain 1n aposition of presentation while the other jack and form are beingactuated to level the sole of a shoe and return the jack and form to aposition .of presentation. When the jack andform are returned to aposition of presentation the arms upon which they are supported' areautomatically disconnected from the the driving shaft is automaticallystopped. ln order to vary the number of pressing operations to which thesole of the shoe is subjected the machine is provided with meanscontrolled by the thickness of the sole of the shoe upon the jack fordetermini ing the number of oscillations imparted to the arms upon whichthe jack and form are supported before the jack and form are returned tothe 4position of presentation'.-

' returned to the position of presentation.

lIn the drawings 1 indicates'arms, two in nu1nber,`pivotally,mountedat 3in the upper front portionof the machine frame 4.`

5- indicates two armspivotally mountedl i in the machineV frame at 6belowthe arms 1.

The sole pressing formsyare supported upon the arms 1 and the jacks aresupported upon the arms 5, the arrangement of the arms 1 and 5 beingsuch that the forms upon the arms '1 coperate with the `jacksupon thearms 5 to subject the soles of shoes supported upon the jacks to arolling pressure when the arms are oscillated.l The jacks, which are notillustrated, may be of'any suitable construction adapted to supportashoeand may be secured to the arms 5 in any customary or desired manner. Theforms are also not shown on the drawings and may be of any usual ordesired construction.

These fomnsare secured, as is common in this-class of machines,.`toform-carrierseach of which consists of `a plate 7 provided with,

a stem 8 mounted-to slide in one of the arms 1. `Each form carrier ispressed down` wardly by al series of springs 9 supportedy upon a vrod'10 and interposed between acol-l lar on therod and anl upwardlyprojecting portion of the "plate 7 the u per'end of the rod l() having ascrew-threa ed4 engagei'nefut` with a *lug projecting from the arm llandhaving a sliding engagement "with thet up'- wardly'extendin portion ofthe plate The form carrier 1s also pressed .downwardly by means of aseriesof s'prings'll surrounding-a-rod 12 having a screwlthreaded ,en-`gagen'ient at its upper end' with the larm l and having a'slidingengagement at its lower end with the stem 8, the springs beinginterposed betweenja collaron the rod and the upper end of the Istem-8.`The form carrier is thus yieldingly forced toward the jack and isallowed to rise as the jack and form are swung' from the front towardthe rear of the machine to bring the form into conf tactwith the sole ofthe shoe and tov subject the sole to a rolling pressure. i 4It willbe`evident that the ldistance' to which the form carrier is raised willvary 'with the thickness of the sole of the shoe being operated upon andthis varying movement of the form carpressing `operations to which thesole is subjected as will be hereinafterv described.

' Each ofthe arms 1 and 5 is provided with a toothed segment 13 whichmeshes with one of four worms 14 upon-two vertical shafts 15. Each shaft15 is provided with a gear 16 which meshes with a gear 17 upon the upperend of a' short vertical shaft 18. vThe shaft 18 is provided at itslower end witha bevel gear 19 which meshes with a bevel gear"20 upon themain driving shaft 21. The above-described construction is such thatboth shafts 15 are rotated in the same direction, the direction ofrotation of the shafts 1'5 depending on the vdirection of rotationof'the shaft 21.

In order to oscillate either jack and its cooperating form backward andforward from -a position at.the front of the machine'to levelthe sole ofar shoe-sup orted upon the jack the main driving shaft 21 is rotatedalternately in opposite directions. Tol this end driving pulleys 22 and23 are mounted to rotate loosely upon opposite ends of the driving.shaft 21 and to bey capable of moving longitudinally thereon. Thesepulleys are continuously driven in opposite directions from any suitablesource of power.

-Rigidly secured to the opposite ends of the main driving shaft arefrictional clutch members 24 and 25 with which coperating clutch membersupon the pulleys 22 and 23 are arranged to be brought into engzugement,vin order to clutch either pulley to the drivshaft. The pulleys 22 and 23are pro- 1n vided with grooved collars which are engaged respectively byarms'26l and 27 secured to a shipperrod 28.

The arrangement of the' shipper rod 28 andthe arms 26 and 27 issuclrthat'when the shipper rod is in its 4-medial vposition both pulleysare disconnectf ed from the clutch members 24 and 25 and vrotate looselyupon the driving shaft. Then y i the shipper rod is moved in onedirection the pulley 23 is moved into enga ement with the clutch member25 andthe rivingshaft is rotated in onedirection and when :the ship.'per rod is moved in the 'opposite direction -the pulley 22 is movedinto-engagement with vthe clutch member 24 andthe direction of rotationof the driving shaft is reversed.

In the machine shown in the drawilpigs, means are provided forautomatically actu'- ating the shipper rod 28 to reverse the direcjackandare finally returned to the position Vof presentation at the front ofthe machine. The means for actuating the shipper rod 28 y ,to reversethe direction of rotation of the rier is utilized to determine thenumber of driving shaft will be clearly understood ilo from aninspection ofFigs. and 6. 4Referring to "these figures 29 indicates aWorm upon the main driving'shaft which is engagedA by a traveling nut30.This nut has l atpm and slot connection with the upper end a lever 31pivoted at 32 to the frame of the machine. The lever` 31 is connectedbyl `means of a link 33 to an arm 34 projecting from the hub of a bellcrank lever 35 `pivoted' at 36 to the frame'of the machine. The

' two arms of the b'ell crank lever 35 are connected by means of links37 to the distance arm's 38 pivotally mounted upon a shaft 39 wheel andthe shaft 39 to whichit is secured are intermittently rotated as the nuttravels by leaf springs 42.

upon opposite sides of a ratchet wheel 40 1.5

back and forth on the worm 29, one pawl 41 being in engagement with aAtoothwof the ratchet wheel. when the nut is traveling in one directionand the other pawl being in l engagement with the. teeth of the ratchetwheel when the nut is traveling in the opposite direction. Also securedto the shaft 39 is aI disk 43 provided on one face with a cam groove 44and on the opposite face with a series of cam projections 45. The camgroove 44 is engaged by a roll or stud upon the lower end of a lever 46pivoted at 47 to the frame of themachine and having a in andislotengagement at itsupper end with a collar 48 mounted to slide upon theshipper rod 28. Two collars 49 and 50 are secured to the' shipper rodupon opposite sides ofthe collar 48 and coiledsprings 51 and 52 surroundthe shipper rod and are interposed between the collars 49 and 50 and theloose collar 48. The c'ollar 50 ha'sra pin and slot 45A lever 53 pivotedat\54 to the frame ofthe machine and. provided at its lower end withconnection with the upper end of a locking a lroll or stud which isarranged to b e engaged by the cam projections'45 on lthe disk 43. Thearrangement of the -levers 46 and 1 53,t he cam groove 44 and the. camprojections 45 is such that as the shaft 39 and the cam disk 43 securedthereto are rotated the shipper rod 28 is held from movement by' theengagement of the stud onthe lower endof thelockin lever 53 with eitherthe outer or inner sur ace of one of the cam projections 45 until thecollar 48 has been moved by means of the lever 46 and cam groove 44 tocompress one of the springs 51,01-l 52. After the spring has beencompressed the continued movement of the cam disk 43 'Y movesthe camprojection 45 out of engagelment with-thc stud on locking leverv 53,thereby releasing the leverand allowing the spring which has beencompressed to move. t e shipper rod 28 to reverse the direction ofrotation of the driving shaft. The stud on the lower end of the lockinglever 53 1s alternately engaged by the outer and inner surfaces of thecam projections 45 so that the shipper rod is held alternately in itsextreme positions to the right and to the left with one of the drivingpulleys clutched to lthe driving shaft.

The machine illustrated in the drawings is designed to impart to thejack and form connected to vthe driving shaft a relatively long movementfrom a position of presentation at the front of the machine to aposition of pressure and thereafter either to return the'jack and format once to the position of presentation at the front of the machine orto impart a number of shorter intermediate movements to the jack andform and then return them to the position of presentation. The ratchetWheel 40 illus-v turned to the position of presentation at the front ofthe machine,rmeans are provided for adjusting the connections betweenthe traveling nut 30 and the ratchet Wheel 40 to allow the nut to travelvarying distances before moving the shaft 39 through an eighth of arevolution. To this end tne link 33 is connected to the lever 31 bymeans of a pin passing through the slot 55 in the lever 31.. When thelink 33 is raised with the pin in the upper portion of the slot it willbe evident that a shorter travel of the nut 30 is required to move theshaft 39 through an eighth of a revolution than when the link 33 is inits lowered position with lthe pin in the lower portion of the slot 55.The link 33 is automatically raised and lowered during the operation ofthe machine as will be' hereinafter described.v When the machine isatrest with the forms and jacks started'into operation the link 33 israised during the inward movement of the jack and form and; is-heldraised until the jack and form enter upon their nal outward 'movementDurmg the final outward movement the link 33 is lowered and the nut 30is allowed to travel back to its original eX- end the nut is,

at the completion of the 4leveling operation.

, The final Imovement 'of' the nut 30' t its eXtreme position at theleftas viewed in Fig. 5 is utilized to disconnect both driving `pulleysfrom the main driving shaft. To this 56', see Fig. 4) which is varrangedto engage a movable stop 57 pivotally mounted upon a' block `58 lwhichis pivoted so as to be cap p'able of'swingmg vertically upon 'the frameofthe machine. When the nut reaches itsy extreme -position at the leftthe projection 56 contacts with the stop 57 and moves `into the theshipper rod is actuated 'so that when the it into thepath of a stopcollar 59 4secured to the shipper rod.

In the machine illustratedlin the drawings, bothl jacks and theircoperating forms are disconnected from the driving shaftv when the jacksand forms are in the p osition .0f presentation at'the frontof themachine. Either yjack and its cotiperating form can be connectedto thedriving shaft so as to be actuatedto level the sole of a shoe and toreturn to a position of presentation, the

other jack 'and form remaining in the posi-v tion of presentationdisconnected from the drivingshaft. In order to allow the jacks andforms to be connected to and disconnected from thewdriving shaft thegears 16 -are mounted to` rotate loosely upon the are provided withclutch members which are., arranged to be engaged by clutch members 74splined upon the shafts and mounted to move longitudinally thereon. Eachclutch member 74 1s acted upon by a spring 75 coiled around a shaftl 15and interposed between a fixed collar 76 and a clutch member 74, g thetendency of the springs being to force the clutch members 74 into`engagement with the clutch members 4on the gears 16. Each clutch member74 is engaged by an army 77 secured to the upper end ofa rod 70. Aspring 78 surroundin 70 and interposed between the bearing for the upperend of the rody and the arm 77-`tends to lf orce the rod downwardly; Aprojection 79 on a plate secured to each of the arms 5 is arranged toengage a block 80 secured to the rod 7 O when the arm -5 is swungtoreturn the jack to its position `of. presentatiom the engagement of theprojection 79 with the block 80 lifting theirod 70 to automaticallydisconnect the clutch member 74 from lthe clutch member the clutchmembers jack remains in the position of presentation. When the machineis thrown into operation either treadle 64. the oscillation of thecorresponding rod 70 moves the block 80 out of engagement with'theprojection'79 and allows the clutch member 74 to move into engagement'with -the clutch member of the lgear 16.

In order to insure that each jack and its coperating form shall bedisconnected from itsactuating mechanism when returned 'to a position ofpresentation, the projections 79 are so arranged as to bebrou ht intoengagement with the blocks 80 be ore the rotation of the main drivingshaft is stopped; and inv order to in'sure that each jack and form shallbe connected to its actuating 'mechanism at the same point in the travelby the depression of y j ation of the rod. 70 to move the blocks 80 outthe driving 'shaft has been thrown into operation and the nut 30 hastraveled a certain distance on the worm 29. The means for preventing theactuation of therods 70 to remove the blocks 80 from engagement with theprojection 79 until thenut 30 has trav- `eled a certain distance on'fthe'worm 29 consists of a stop plate 60a adjustably secured to4 the bentlever 60.' VWhen the; machine is started into operation bythe depressionof a treadle 64 the'plate 601- contacts with th`e nut 30 or itsprojection 56 'and prevents the treadle 4being depressed a suiiicientdstance to actuate a rod 'so as :to remove a block from engagement withaprojection 79,. The treadle v64 is, however, depressed a suiicientdistance to move the stop- 57. out

of engagement with the stop collarl59 on the; shipper rod'. After thedriving-shaft 21 is thrown into operation the nut 30 is moved frombeneath'the plate 60a^`and the treadle is allowed to complete itsmovement so as to lactuate the rod 70 to remove the block 80 Afromengagement with the projection 79.

It will be evident that the number of pressing operations -to which thesole of a shoe is subjected will depend u pon the timfe during vtheoperation lof the machine at which the link 33 is moved into its lowestposition. ln the machine illustrated in the -drawings the link 33'ismovedfbymechanism which is thrown into operation at Aa time during theoperation of the machine determined by the thickness of the sole of theshoe being operated upon. The link 33 is connected by means of a link 81to one arm of a lever v82 pivotally mounted upon a rod 83 so as to becapable-otmoving longitudinally thereon'. The other arm of the le- !ver82 is provided with a roll or stud 84 which is arranged to be engaged bya cam 85 secured to the shaft 39. Vhen the stud 84 is upon a raisedportion of the cam 85 the link 33 is held in its lowered position, butwhen the stud is out of engagement with the cam or in contact with a lowpart of the cam, the link 33 is held in its raised position. During thegreater portion 'of theoperation of the machine the stud 84 is -held outofthe path 'of movement of the cam 85v by means of a spring 86surrounding the rod 83 and tending to force the .lever 82 to the left asviewed in Fig. 4. The lever 82 is moved fto bring the stud 84 into thepath of movement of the cam 85 by means of a timing cam 87 i secured tothe shaft 39. This timing cam is provided with a 'series of cam groovesas is clearly illustrated in Figs. 8 and 9, one of which, while themachine is in operation, is in engagement with a finger projecting froman arm 88 pivotally mounted upon a sleeve 89 mounted upon the rod 83l`so as to move longitudinally thereon. The arm 88 is pressed toward thecam 87 by means of a spring 90. When the machine is at rest, thearm 88is in its entreme position at the right as `.viewed in Fig, 4, theingenof the arm being at the end Otone of the cam grooves.

eling'a shoe, the arm 88 is raised by means engages the end of the armand the arm is 'moved to the left and its linger brought into engagementwith vone of the grooves of the timinggcam 87. The point on the timingcam which is engaged by the finger of the arm 88 is determined by astopcam 92 which is mounted to rotate loosely upon the shaft 39 and whichcovers up a portion of the timing cam. A bevel gear 93 is securedl-tothe stop cam 92 and meshes with a bevel gear 94 upon the lower` endof a vertical A.shaft '95. To the upperend of the shaft 95 is secured agear 96 with whichmeshes a rackf97 carried by an arm 98 secured to a rod99 mounted to slide 1n bearings 1n the .upper front portion of themachine frame.

To the rod 99 are secured two segmental -connections between the formcarriers and the stop cam 92 are such that the upward movement of eitherform carrier causes a rotation of the stop cam, the amount of rotationdepending uponA the extent of the "upward .'movement of the form carriervwhich in turn depends upon the thickness During the lirst inwardmovement of the jack and form 1n levshaped plates 100 againstthe sidesot' which the' upper ends of arms 101 bear. The arms of the sole of theshoe being operated upon.

Acoiled spring 104 surrounding one end of the rod 99 and interposedbetween a collar on the end of the. rod and one of the bearings for therod tends to hold the rod in its extreme position toward the left asview in Fig. 3. The stop cam 92 illustrated in the drawings (see moreparticularly Figs. 10 and 11) is provided with three portions markedrespectively a, Z) and c, which are designed to 4be engaged by thelinger of the arm 88 and determine the point on the timing cam which isto be engaged by the arm. In the machine shown in the drawings, ,if theshoe being operated upon has a thin sole, the stop cam 92 will berotated so as to bring the' portion a of the cam into the path ofmovement of the finger on the arm 88 and the arm will be engaged by thetiming cam so as to be moved a sutlicient distance lo bring the stud 84oli the lever 82 into the path of movement of the cam 85 during the Erstoutward movement t the porton of the in its medial position by 88 andthe lever cam 91 and the stu esame of the jack and form. When,therefore, the stopcam 92 is set to cause its portion a to engage thefinger of the arm 88 the jack and form will be moved from a positionofpresentation toia positiontjof pressure and immediately returned to aposition of presentation.v When thicker soles are o erated upon the cam92 ciently to bring either into the path of movethe' portion b or c onthe arm 188 and the ment of the finger ,arm will not be moved by thetiming cani to of the lever 82 into the f brlng the stud 84 path ofmovement of the cam 85' until a number of shorter intermediate movementsare imparted to the jack and form before position of presentabelngreturned to the tion. In' the machine shown in the drawings one shortermovement in each dlrection will be imparted to theiackvv and form when athe portion. b of the stop cam 92 limitslthe movementy of the farm? 88and two interl'ne' diate shorter movements in each directionA will beimparted to the jack and form when stop cam limits the movement ofthe'arm 88. is .raised and* moved backward to lbring the finger thereon intoengagement" withV a-I groove of the timing cam, the finger ispre-lvented from drepplng into a groove until it strikes the st p. cam bymeans of a spring pressed fingerlO (see more particularly Ilig..12).

The operation ofthe machine above described is -as'ollows :f-When themachine is 'at rest bothl the jacks and their coperating" forms are inthe position of presentation at the front ofthe" machine, both .rodsare".

held raisedby the enga ement of projections 7 9 with blocks 80, the sipper rod 28 is held the engagement ,of the stop collar 59 with the stop57 andboth the vdriving pulleys are .disconnected from the drivingshafts. The spring 51 surrounding the shipper rodis compressedtending toas viewed force the shnpper rod tio-the left in Fig. 6 an the stud onthe lower end of ythe lockinglever 53 'is opposite a space be-I tweentwo of' thefprojections 45. The arm 82 are in their eXtreme-position atthe right 'as viewed in Fig. 4, the end of the arm 88 bein in engagementwith the d 84 of the-lever 82 being upon a raised portion of the cam 85.A shoe "having been placed upon one of the jacks, the 'treadle onthatside of the machine is depressed. The depression of the treadle-first releases the shipper rod as has been described and then. releasesthe rod 70 connected with the jack which is to be thrown into operation.The driving shaft is thus connected to one of the driving the jack uponwhich the shoe has been placed and its coperatiug form are connected tothe driving shaft.

a described. During When the arm-88 i time acting to path combination,

pulleys andl During the first inward y movement of the carrler 1s raiseddescribed. During the inward movement of the jack and form and after'thestop cam 92 has been operated, the cam-,91 raises the arm 88 and allowsthe spring ,86- to force the lever 82 and the arm 88 to the 'leftasviewed in Fig. 4. The move ent of the arm 88 and of the lever82 totheleft is limitedl by the contact ofthe linger of thev arm 88 with thestop cam 92, the linger dropping into one of they grooves of the timingcam 387. The finger engages one of thestraight portions ofthe grooveandis moved bythe inclined 'portion of the v groove during the outwardmovement ofthejack and'form. :The driv'- ing shaft iis rotatedalternately in lopposite directions and the'shaft 39 is rotated step bystep throughl the; connections hereinbefore the rotation of the shaft-.

39 they arm -88 is moved toward the right as lviewed in Fig`.f4 by .theengagement of the 'timing cam with the finger of thearm 88 and duringone ofthe outward movements of the jack andfform the cam 82 into the thecam 85, which acts to depress the link and thereby 4delays the action ofthe reversing mechanism until the jack and form are returned to t-hemovement ofthe nut 30 to its .extreme positi'on at ftheleft (as viewedin Fig. 5) at this` a throw the stop 57 into the of movementof the stopcollar 59 so as to arrest the shipper rod 28 in its medi-al positionwhen the reversing mechanismy operates.
